Hi Valeria, If you mean straight lines between CA atoms, sorry no, there is no CA trace display in ChimeraX yet. It is #694 in our ticket database.
You can show a spaghetti-type ribbon that goes through the exact CA positions but is curved in between, e.g.
cartoon cartoon style arrows f xsect oval width 1 thick 1
as shown for the purple protein in rightmost image here: http://www.cgl.ucsf.edu/home/meng/chimerax/docs/user/commands/cartoon.html#subcommands
In that case you could use different width and thickness values. If you want to additionally show CA balls, maybe something like:
cartoon suppressBackbone false cartoon style arrows f xsect oval width .5 thick .5 show @ca style @ca ball
… as shown in attached image. I hope this helps, Elaine ----- Elaine C. Meng, Ph.D. UCSF Chimera(X) team Department of Pharmaceutical Chemistry University of California, San Francisco

Dear all, I was wondering, is there an option to just show a Ca trace in ChimeraX? If yes, can one modify the width of it? Thanks a lot in advance, Valeria
